CHURN-DASHER.

SPECIFICATION forming part of Letters Patent No. 507,065, dated October17, 1893.

Application filed July 5, 1893. Serial No. 479.626. (Nomodel.) i

To all whom it may concern.-

Be it known that I, JAMES MATERSON OHAD- WICK, a citizenof the UnitedStates, residing at Gadsden, in the county of Etowah and State ofAlabama, have invented certain new and useful Improvements inOhurn-Dashers; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The object of my invention is to provide a simple and inexpensive churndasher which serves to violently agitate the milk to effect theexpeditious separation of the butter particles from the milk; and afurther object is to provide means which, in addition to agitating themilk, serves to cushion the downstroke of the dasher and aids inreturning the same on its upstroke.

With these ends in view, the invention consists, first, in the dashercomprising a socket for the dasher-staif, a series of radial wings orwebs, and a series of inverted conical cups each carried by one of saidradial webs or wings and provided in its upper end with an opening overwhich is fixed a breaker-hood that lies in the path of the jet of milkthat flows through said inverted cup on the downstroke of the dasher;secondly, a spring connected to the lower end of the dasher sta andhavingits lower coil bent in a horizontal plane and forming a flat baseso that the dasher will have a firm bearing in the churn receptacle;and, thirdly, in the method of attaching the spring and dasher to thestaff which overcomes the tendency of either part to become detached.

In the accompanying drawings, forming a part of this specification, Ihave illustrated the preferred embodiment of my invention, in Which-Figure l is a side elevation. Fig. 2 is an inverted or bottom-plan view.Fig. 3 is a vertical sectional view on the plane indicated by the dottedline -w of Fig. 2.

Like letters of reference denote corresponding parts in all the figuresof the drawings.

My improved dasher can be used in any kind of a vessel or receptacle.

The dasher proper consists of a longsleeve or thimble A, a series ofradial wings or webs B, and a series of cups O, all of which arepreferably castor formed in a single metal for simplicity and cheapnessalthough one or more of the parts may be made separate, of any suitablematerial, and fastened together in any approved manner. The cups O aremade in the shape of inverted cones with their broad open endslowermost, and each 6o cup has an opening c at its upper end, over whichopening is arranged a breaker-hood D that partially covers the opening cand lies in the direct path of the jet or stream that is forced throughthe cup on the downstroke of the dasher. This breaker-hood D ispreferably integral with the cup and it is so arranged or formed as toleave side openings or passages d for the escape ofthe milk that passesthrough the cup-opening O and is deflected 7o and `broken by thebreaker-hood D. The wings or Webs B extend radially from the thimble orsleeve A, and its outer edge is joined or united with the cup C, saidcups lying at suitable distances from each other and the staff.

The thimble or sleeve A is extended a suitable distance below the lowerextremities of the inverted cups, and in this thimble is titted thedasher staff E which has its lower 8o end terminating practically flushwith the lower'extended end of the thimble.

F is a spring that serves to agitate or churn the milk, to cushion thedownstroke of the dasher and thus avoid any danger of breaking the cupsC, or bottom of the churn and to assist in returning the dasher on itsupstroke. This spring consists of a wire bent into the helical formshown, the coils gradually increasing in diameter from the sleeve 9o andstaff to the lower larger coil fof the spring. This lower coilfis bentso it lies in a horizontal plane and the free end of the wire isattached to said coil, thus forming a fiat base designed to restsquarely on the bottom of the receptacle or vessel. The upper end of thespring is coiled or bent one or more times around the lower end of thesleeve or thimble A, and the upper end of the wire is bent to form thestraight arm f which is loo passed centrally through the lower end ofthe dasher staff and sleeve A, to firmly secure the spring, stafl andthimble together and prevent accidental separation of the parts.

I do not strictly confine myself to the use of the spring in connectionwith the dasher, as it is evident that the dasher can be dispensed withand the spring used with the sta, or vice versa; but for greaterefficiency in operation and to churn the butter more quickly, I preferto use the dasher, the spring and staff combined and arrangedk as hereinshown and described.

The operation may be briefly described as follows:-The milk is placed inthe receptacle or vessel and the dasher then adjusted therein so thatthe fiat base coil f is adapted to rest squarely on the bottom of thevessel. The dasher is reciprocated up and down by hand, or by power, andthe spring and cups agitate and churn the butter very quickly. Ou thedownstroke of the dasher, the spring is compressed to cushion thedasher, and the milk is caused to pass through the inverted conicalcups, in which it is condensed and caused to jet or spurt through theopenings o and to strike against the breaker-hoods D, thus violentlyagitating the milk. On the upstrokeof the dasher, the spring reacts oris extended to assist the upstroke, and by thus Working the dasher upand down the butter can be churned in a very short time.

I am aware that changes in the form and proportion of parts and detailsof construction of the devices herein shown and described as anembodiment of my invention can be made without departing from the spiritor sacrificing the advantages thereof,and I therefore reserve the rightto make such changes and alterations therein as fairly fall within thescope of the same.v

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. A churn dasher consisting of the sleeve or thilnble, a series ofinverted conical cups carried by said sleeve and each cup having anopening at its upper end, and provided with a breaker hood situated oversaid opening in each of said conical cups, substantially as and for thepurposes described.

2. A churn dasher consisting of a stalreceiving sleeve, a series ofinverted conical cups on said sleeve and each carrying a breaker-hoodwhich lies over an opening in the upper end of the cup, and a coiledspring situated below the stati-sleeve and fastened at its upper endthereto, substantially as and for the purposes described.

3. A churn dasher consisting of a sleeve provided with radial Wings, aseries of inverted conical cups rigid with said wings and each carryinga break-hood which lies over an opening in the top of said cup, a stafffitted in the sleeve, and the spring arranged below the strait andsleeve and having its upper end passed through and fastened to thesleeve and staff, substantially as and for the purposes described.

In testimony whereof I aix my signature in presence of two Witnesses.
